How did our primate ancestors make it to the americas 50 million years ago, bears about 38 mya, or the cougars 8 mya? But humans entered the americas about 13500 years ago. Shouldn't the trend be that even the earliest hominids would have migrated in similar patterns? Wouldn't logic suggest that we should find some kind of hominid in the americas? I hope every knows that I ask with the sincere idea of learning the answers to my question.
The first primates apparently evolved in China more than 55 million years ago. But primates almost as old at those have been found in Mississippi. The ancestors of many North American species made their way hear from Asia via the Bering Sea region. Marsupials evolved over 125 million years ago in China, and spread from there. Hominids, as has been pointed out, have not been around all that long. As for how long humans have been in the western hemisphere, he is an article that should catch you up on the current thinking:

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
